Definition
Test-driven development refers to a programming style in which three central activities (programming, coding and testing) activities are tightly interwoven. It follows a specific set of rules:
- Write a ‘single’ unit test describing an aspect of the program.
- Run the test first time, identity the missing component after failure.
- Write more code, in the simplest way. Pass the test.
- Refactor the code to conform to simplicity criteria.
- Keep on repeated ‘testing’ over time.
